Introduction
In Part 1, we introduced financial ratio analysis as your early warning system and explored how it reveals hidden problems beneath seemingly healthy financial statements.
We saw how the combination of declining inventory turnover, increasing Days Sales Outstanding, and rising debt can trap millions in cash despite growing revenue and stable margins.
Today, we'll explore the five essential financial ratios in depth and show you exactly when and how to take action when ratios reveal potential problems.
TL;DR - What to Expect:
Check how to interpret and act on the 5 most important ratios in your business, with a decision tree + worksheet to guide you.
The 5 Essential Financial Ratios for Managers
Let's explore each of these critical ratios, what they mean, and how to use them to make better business decisions.
Ratio 1: Current Ratio (Liquidity).
What it measures: Your ability to pay short-term obligations.
Formula: Current Assets ÷ Current Liabilities
Ideal range: Generally 1.5-2.0, but varies by industry
Warning signs:
Ratio below 1.0: Potential inability to meet short-term obligations
Steady decline over time: Deteriorating liquidity position
Ratio far above industry average: Potentially inefficient use of assets
Action steps if problematic:
Review payment timing for both receivables and payables
Evaluate inventory levels and identify slow-moving items
Consider renegotiating payment terms with vendors or customers
Establish a short-term line of credit for a liquidity buffer
Ratio 2: Inventory Turnover (Efficiency)
What it measures: How efficiently you manage inventory.
Formula: Cost of Goods Sold ÷ Average Inventory
Ideal range: Highly industry-specific, but higher is generally better
Warning signs:
Declining trend: Accumulating slow-moving inventory
Significantly below industry average: Operational inefficiency
Erratic fluctuations: Poor inventory management systems
Action steps if problematic:
Implement category-level inventory analysis
Establish maximum inventory levels based on sales forecasts
Identify and liquidate obsolete or slow-moving items
Review purchasing practices and order quantities
Consider just-in-time inventory management for appropriate items
Ratio 3: Days Sales Outstanding (Collection Effectiveness)
What it measures: How long it takes to collect payment after a sale.
Formula: (Average Accounts Receivable ÷ Annual Revenue) × 365
Ideal range: As low as possible, but typically 30-45 days
Warning signs:
Increasing trend: Customers taking longer to pay
Significantly above industry average: Subpar collection processes
Large gap between payment terms and actual DSO: Poor enforcement
Action steps if problematic:
Review credit policies and tighten standards for new customers
Implement automated payment reminders
Offer early payment discounts
Establish formal collection procedures for overdue accounts
Consider factoring for problematic accounts
Ratio 4: Debt-to-EBITDA (Leverage)
What it measures: Your debt burden relative to operational earnings.
Formula: Total Debt ÷ EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization)
Ideal range: Generally below 3.0, but varies by industry
Warning signs:
Increasing trend: Growing reliance on debt financing
Ratio above 4.0: Potential difficulty servicing debt
Approaching debt covenant levels: Risk of default
Action steps if problematic:
Prioritize debt reduction over expansion
Investigate refinancing options for better terms
Review capital expenditure approval process
Consider equity investment for growth initiatives
Implement cash flow forecasting to prevent further deterioration
Ratio 5: Return on Invested Capital (Profitability)
What it measures: How efficiently you generate profits from capital.
Formula: NOPAT (Net Operating Profit After Tax) ÷ Invested Capital
Ideal range: Should exceed your cost of capital by at least 3-5%
Warning signs:
Declining trend: Deteriorating capital efficiency
Below cost of capital: Destroying shareholder value
Significantly below industry average: Competitive disadvantage
Action steps if problematic:
Analyze profitability by product line, customer, or business unit
Reevaluate pricing strategy and cost structure
Divest underperforming assets or business segments
Focus capital allocation on highest-return opportunities
Consider restructuring operations or business model
The Financial Ratio Decision Tree: When to Act and When to Wait
Not every concerning ratio requires immediate action. Use this decision framework to determine when and how to respond:
Scenario | Response | Timing | Example |
|---|---|---|---|
Single ratio outside range, others healthy | Monitor closely | Quarterly review | Current ratio dips slightly below target |
Single ratio significantly outside range | Focused intervention | Within 30 days | DSO increases by more than 30% |
Multiple related ratios showing problems | Coordinated action plan | Immediate | Both inventory turnover and DSO deteriorating |
All ratios trending negatively | Strategic reassessment | Urgent priority | All five ratios showing consistent decline |
Industry-wide ratio changes | Competitive benchmarking | Within quarter | All competitors experiencing similar trends |
Remember that ratios should be analyzed in context—both in relation to each other and to your industry, business model, and growth stage.
"The three most important words in investing are margin of safety."
The same concept applies to managing business finances—always maintain a buffer against unexpected challenges by keeping your key ratios in healthy ranges.

Success Story - Tesla
In 2017–2018, Tesla’s liquidity crisis flashed warning signs: a Current Ratio below 0.9, sluggish inventory turnover, and a Debt-to-EBITDA over 5.0.
Despite growing demand, negative ROIC and rising cash burn put the company in danger.
Management acted strategically, streamlining production, speeding deliveries, and cutting costs to boost working capital. Optimized payments maintained a low DSO, while new capital slashed debt by billions.
Within 24 months, the Current Ratio hit 1.5, Debt-to-EBITDA fell to 2.5, and ROIC turned positive. Tesla transformed from near-default to a profitable growth engine, using ratios not just to react, but to map sustainable expansion.
These operational changes unlocked billions in market cap growth and turned a near-default company into one of the most valuable brands on Earth.
